Beit known that 1, JAMES ELLwooD JONES,

a citizen of theUnited States of America, re

siding at Switchback, in the county of Mc- Dowell,in the State of`West Virginia, have in vented certain new and usefuimprovements in Loading-Machines, of which the following is a specification.

This invention relates to a machine for transferring material-such as coal,ore,ashes, or other snbstanceswfrom one point to an other; and it is especially designed for loading coal from the ioor of a mine onto the mine-car for carrying it out of the mine.;

rihe loading eticoal in mines has heretofore been generally done by manual labor, as the conditions of the mines were thought to be such as to prevent the practical use ot machines for this purpose, owing to low ceilings, narrow passages, and small rooms in which the work is to he done.

The principallobject of this invention is to provide a loading-machine adapted to operate in the contracted space of a coal-mine for loading onto cars for conveyingit out of the mine the coal shot down by the usual blasting operation, and in carrying ont this object I have devised a simple mechanism, preferably located on a car traveling on a minetrack, adapted to pick up the coal from the mine-floor, elevate it to a point over theminecar, and deliver'it into said car.l

Figure 1 of the accompanying drawings represents a vertical section of 'fa mine-room from which the coal is mined and a side elevation of one forni of this portable loading-v machine disposed therein on the mine-track, the mine-car onto which the coal is loaded hy the machine being indicated by dotted lines. to Fig. 2 represents a plan of u mine-room and a horizontal sectionof the loading-machine on line 2 2 of Fig. 1, parts being omitted or broken out. Fig. 3 represents,` ou an enlarged scale, one xform of the mechanism for vertically adjusting the coal-conveyor on its supporting -carriage Fig. it represents a horizontal section on line 4; 4 of `Fig. 3, also showing said mechanism. Fig. 5 represents an enlarged plan of the portable base of form-car, the oarrlage traveling thereon, J means for moving the carriage on the car,

the loading-machine inthe form of a plat` and a party of the conveyor-frame supported on said carriage. Fig. 6 represents, on an enlarged scale, aside elevation, partly in sec- Ytion, of the machine, showing an endless platform constituting apart of the conveyortrough at an angle thereof and also showing a pusher-rod under control of the operator for pushing the receiving-car away from the oo loading-car to distribute the delivery throughont the receiving-car during the loading operation, the receiving or mine car being indicated in diiterent positions by dotted lines. Fig. 7v represents, on an enlarged scale, a ver- 65 tical section on line 7 7 ofxFig. (i, showing actuating devices t'or said pusher-rod. Fig.

Fig. 10 represents a side elevation of the parts shown in Fig. il; Fig. l1 represents an enlarged view of the adjusting mechanism for the conveyorframe shown in Figs. 9 and. 10. Fig. 12 rep- 8o resents a side elevation of the conveyor-frame mounted on the carriage, the lower portion of the former being hinged .to the upper-portion thereof. Fig. 13 represents, on an enlarged scale, afragment of the lower portion of the'85 inclined conveyor-frame, the front extension thereof, a portion of the endless conveyor, and a section of the top guide-plate on said extension for the conveyor. Fig. 14 represents a transverse section through one-half 9o of the conveyor-frame and conveyor, showing theelevator-trongh provided with a flanged guide for holding the nights in contact 'with the trough and a rearwardly-extending shoe on the latter for engaging the guide to hold the flights at right angles to the trough. Fig.

Fig. represents, on an'enlarged scale, a side elevation of theconVeyer-frame and its horizontal front' roo extension, the lower part of said frame being 'hinged to the uppei` part and provided with means for raising and lowering it and said extensionbeingadjnstable at different angles to 'lit the floor of the mine. Fig. 17 represents, on an enlarged scale, a side elevation of the lower end of the inclined conveyer-frame and its horizontal front extension, showing means for adjusting said extension to adapt it to irregularities of the mine-floor and to keep taut the endless chain of the conveyer. Fig. 18 represents means for locking the loading-car on track.

The same reference-numbers indicatethe same parts in the different gures.

A vehicle or car 1() preferably constitutes the portable base or platform of the machine and is adapted to travel on a track laid through the m'ine in the ordinary manuel'. This car is preferably provided `with means for locking itin position on the track. Any suitable means maybe employed-for holding the car steady. The means shown in Fig. 1 comprises a bar l1, pivoted to the bottom of the car and adapted to engage the bottom of in Fig. 5, and by a spring-catch the" room of the mine. for holding the car against movement in one direction. A hook 12 underneath the car serves to support the free end ot' the bar when not in use. For holding the car against movement in the other direction one of the axles is provided in Fig. l with a ratchetwheel 13, and an adjustable hand-lever 14, pivoted on the base 10, is pro,

vided with a tooth 15, adapted to engage said ratchet-wheel, and a rack 16 serves to hold said lever in adjusted position. Another meanslor the purpose is shown in Fig. 18, where a toothed wheel 17 on one of the axles is engaged by a spring-rod 18, actuated by a lever 19, for holding the car against move-Y ment in either direction. Any other suitable clutch mechanism may be employed for this purpose.

The car 10is provided with an arc-shaped track disposed thereon in a transverse relation to the track on which the car travels. This track may extend beyond the sides of the carand form an arc of a, circle ot' which the center is beyond and at the rear ot the car, as indicated by the'star Y in Figs. 1 and 2. The arc-shaped rails 2O and 25, composing the track, are concentrically disposed on the car one in front'of the other, the'front rail being longer than therearrail. The sideex- Y tensions of the front rail are adapted to fold inward toward the car to enable the car to travel through narrow passages, each lateral extension being connected with the central portion by a hinge 2l on one side, as shown 22 on the other side, which locks the rail in ,open position. These rails may be constructed in any suitable form. ln Fig. 1 the rail 20 is shown in the ytorm of a l upper face with rack-teeth 23, and in Figs.

2, 5, and 6 it is also provided-with rack-teeth andalong its side 'with vertical flanges 24.

l 5 and (5 with rack-teetl127 and Fig. 9 the rack-teeth are omitted from the In Figs. l and 2 the rear rail 25 is provided with a ribshaped upper face 26 and in Figs. flanges 28. In

A carriage 30 is movable on tho car 10, and the means for taking up, elevating, and delivering coal are mounted thereon. This carriage is preferably` mounted on two radiallydisposed axles 31 and 32,provided with wheels adapted to travel on the rails 20 and 25. hason its front side a short post 33 and on its rear side a tall post- 34. These posts may be connected by a cross-bar 85, bracebars 36 and 37, and,'as shown in Fig. 10, by a bent top bar 38. Suitable means are provided for causing the carriage 30 to travel to and fro' on the track Aoi" the car 10. A means for this purpose is shown in Figs. l and 5 and omitted from Fig. 2. This means comprises a .beveled wheel 40, fixed on the axle 32 and meshing with a erown-wheel 41 on a vertical shaft 42, carrying a worm-wheel 43. An actuating-shaft 44 is provided with a worm 45, which meshes with the worm-wheel 43 and with a crank 46 or other actuating device.

The worm connection or other means holds j the carriage in adjusted position on the arcshaped track 'of the car 10. Another means for moving the carriage to and fro on the loading-car is shown in Figs. 9 and 10 and comprises a vertical rod 47, journaled in the cross-bar 35 and vtop bar. 38 and provided at its upper end with a hand-wheel48 and atits lower end with a pinion 44, which engages the arc-shaped rack-rail 29 on the car 10.

An elongated conveyer-frame is mounted on the carriage 30 and comprises in its preferable form an inclined frame 50, the front end of which extends downward below the carriage in front of the car 10, being provided at its lowerend with a depressed front exten sion (50, adapted to move laterally with the movement of the carriage in a plane parallel, or approximately so, with the mine bottom or door for taking up the coal or othermaterial and being preferably provided at its upper end with an elevated rear extension 70, adapted to project beyond the traction-car and vmaintain its position over the top of an adjacent receiving or coal car, as 500, for deliv- This manner of angle-iron or other material. As shown in the drawings, it comprises two parallel bars trussed together and straddling the upright posts 33 and 34.

The inclined frame 50 is so supported or constructed that its lower front end 'may be 'raised above the mine-track hr floor of the mine w'hentho machine is moved from place to place and that its front extension 60 may be adjusted to the bottom or door ofthe mine when the machine is in use. In Figs. 1 and 2'the means of support enable the frame to be raised and lowered in the arc of a circle whereof the center is inthe front extension, as indicated at the point X in Fig. 1. This IOO means of support may comprise short arc,- shaped guides 80 and 81, attached at opposite sides tothe front post 33, and longer arcshaped guides 82 and 83, attached to the opposite sides of the rear post 34 of the carriage 30. Dependent arc-shaped bars 84 and 85 are attached to the rails of the frame 50 and play in the guides of the front post, and longer arcshaped bars 86 and 87 depend from the under side of said rails and play in the guides attached to the rear post.

The means for raising and lowering the conveyer-frameand holding it in adjusted position comprise when constructed as shown in Figs. 3 and 11 an arc-shaped rack 90, secured -to and dependent from one side of said frame, and a like-shaped rack 90, secured to and dependent from the other side thereof. A horizontal shaft 91, journaled on the carriage 30, is provided with pinions 92'* and 92",which engage said racks, and at the front end with` a Worm-wheel 93. A vertical shaft 94, journaled in a bracket 95, also attached to the carriage, is provided at its upper end with a worm 96, which engages said worin-wheel, and at its lower end with a crown-wheel 97.

The shaft126 is provided with a small sprocket Wheel 127, and a sprocket-chain 128 passes over said small sprocket-Wheel and over a large `sprocket- Wheel 129, fixed to the shaft of the upper sprocket-Wheel 101 of the endless conveyor. The flights 110 swing around horizontally, or nearly so, with both runs in substantially the same plane at the lowerfront extension of the conveyer-frame and engage coal on the door of the mine, push it up onto and along the trough 52, and discharge it at the upper end of the latter intoa mine-car underneath, then swing around the upper sprocket-wheel 101 and pass down over the guides 5l on the opposite side of the conveyor-frame.

Means are provided at opposite sides of the conveyor-frame at the angle ot' the front extension with the inclined portion thereof for changingthe travel of the chain from an inclined to ahorizontal'or approximately horizontal direction. The means shown for this purpose in Figs. 1 and 2 are two idler sprocketwheels 61 and 62, journaled at opposite sides of the inclined frame, at the lower end thereof. These wheels may be dispensed with, if desired. The front extension of the inclined framel is provided with a top guard-plate 63,

under which the flights travel. This guardplate may serve at its opposite ends as a guide for the chain when the idlers are dispensed with. i

In Figs. 12 and 13 the end of theguar'dplate 63 on the trough side is provided with an upturned lip 64, having an autifrictionroller 65 to avoid friction of the chain on the guard-plate at the angle of the conveyer with its extension'. The under side of the eXtension 60 may be provided with a shoe 6G, adapted to rest and slide on the mine-,doen This llOO `rito shoe may consist of a rounded end of the journal-box supporting the sprocket 100.

To avoid friction o'f the flights at the upper angle between the inclined trough and the rear extension thereof, said trough is out out for a desired distance in both directions from said angle, and an endless platform 55 is mounted underneath to take theplace of the cut-out portion of the trough. This endless platform extends beyond the opening of the trough, so that the ends of the latter-.will overlap the platform. The platform travels over pulleys 56 and 57 at opposite ends ofthe loop and over an intermediate pulley 58 directly in the angle to prevent the sagging of `the platform. The platform moves with` the flights, avoiding friction and carrying the coal.

The rear extension 70 ofthe con Voyer-frame preferably projects to a point over the rear portion of the adjacent receiving-oar to be filled, and means are provided for separating the cars during the loadingr operation,'so as to bring the delivery end of the loading despectively, to

` reinforcing andlocking.

vice near the front lformed in two sections,

portion of the receivingcar. For this purpose means are provided on the loading-car under the command of the operator for pushing the receiving-car'away from the loading-car as the loading proceeds 'or at any time during the loading operation. Fig. 1 shows a means for this purpose consisting of a rack-bar 130, adapted to slide in guides -131 and 1 32, attached to the carriage 30. This bar may be provided with a bilder 133 at its rear end adapted to engage the receiving-car-andpush it away from the loading-car a desiredv distance to secure a proper delivery of the material in the front portion of the receiving-car.- The means for actuating Ithe rack-bar may consist of a horizontal shaft 134, journaled on the carriage and provided with a pinion 135, engaging said rackbar, and a crank or hand-wheel 136 in convenient position for engagement by the operator. The rack-bar 130 may be provided with a hook 137 at its front end, as shown in Fig. 8, whereby it may be used as acoupling device for a link 138, attached to a receivingcar. In this case the cars may be separated at the beginning of the loading operation and. gradually or intermittently pulled together during the progress thereof.

Another means for support-ing and adjusting the conveyer-fratne is illustrated in Figs.

10 and 11, in which said frame is adapted toI swing in a vertical piane. 1n this case screwthreaded sleeves 140 and 150 are secured, re-

the upper ends of the pests 34 and 33 ot the carriage 30, and vertical adjustable screw-rods 14-1 and 151 are supported in said sleeves. The rear screw-rod 141 is provided at its lower end with a transverse bar 143, which projects laterally and engages hinge-straps, as 144, attached to the opposite rails of the inclined frame, saidbar serving as a pivot or pintle on which the frame swings. The upper end of this rod is provided with a crank 145 for operating it to raise and lower theinclined frame. The front vertical screwrod 151 is alsoprovided with a transverse bar 153, which projects laterally on opposite sides of the frontpost and engagesrecessed lugs 154,8ecured to the opposite rails of the inclined frame. This screw-rod is also provided with a crank 155 for raising and lowerving it. The recessed lugs permit a'play of the inclined frame on the transverse bar 153 of the frontscrew-rod, whereby the screwrods mayv be raised or lowered independently of each other and the .frame adjusted at different angles of inclination.

If desired, the inclined frame may be the upper section 50a being rigidly secured to the carriage 30 and the' lower sect-ion 5 0b being hinged to the section 50, as shown in Figs. 12 and 16. A device is preferably employed at thejoint of the sections to hold the hinged section 5()b in adjusted position. This reinforcing device may consist of a slotted plate 160, secured to the hinged section 50 adjacent to the joint and overlapping the main inclined part 50, and a clamping-bolt 161, secured to the main part and extending through the arc-shaped slot of said plate, as shown in Fig. 16.

Means are provided for raising and lowering the hinged section 50". These means may consist of a segment 162, pivoted onan arm 163, attached to the carrier-frame, a chain 164,con necting said segment with said hinged section, a hand-lever 165 on thelshaft of said segment, a latch 166 on said hand-lever, and a toothed rack 167 for locking said hand-lever in diierent positions, as shown in Fig. 16.

The depressed front extension ofthe carrier-frame may be connected with the inclined portion O-thereot` in such manner that it may be adjusted at an'ineline and still hold the enless chain taut. A means for securing this adjustable connection is shown in Figs. 16 and 17. These means comprise an elongated arc-'shaped strap 170, connected to the' extension 60 and provided with an arcshaped slot 171, overlapping the side of the inclined frame 50, and a clamping-bolt 172, disposed in a hole in said frame 50 and serving to clamp` said strap to the latter. A further connection shown is an extensible brace-rod 180,

composed of a rod 181, hinged toy the frame 50and provided with a right-hand screw-l thread at its outerend, a rod 182, hinged to the extension 160 and provided with a left-hand screw-thread at its outer end, and

a sleeve 183, provided with right and left hand screw-threads at its opposite ends which take onto the screw-threaded ends of said rods. This sleeve is provided with an angular boss for the application of a wrench. The extension 60 may also be provided on the take- IOO up side with a curved shield 67, disposed edgewise and extending from a point on a line with the axis of the front sprocket-wheel -10O back to the lower end of the trough 52.

which is shown in Fig. 1-

This guard-plate, and in section in Fig. 2, lateral bar 68, secured to is supported byl a plate is rounded.

In Figs. 12 and 13 the front take-up extension of the conveyor-frame is shown as integral with the hinged. section 50d of the inclined portion of said conveyer-trame, and it is there designated-as 60. 'lhe front portion of the conveyer-frame may be provided, as

shown in Fig. 12,With antifriction-balls 69,

the frame of the extension 60. The lower end of this guard-i lsaid conveyer.

cross-plate 182, fixed between the rails of the carrier-frame, and at its inner end engages a threaded sleeve 183, secured to said forked bracket 180.

The inclined frame is preferably prof vided, especially on the trough side, with a flanged guideway 59, as shown in Figs. 14 and 15. The inner ends of the flights 110 of the endless carrier engage this guideway and the flanges thereof to hold the flights in horizontal position. These flights are provided at their inner ends on their rear sides with rearwardly-extending shoes 111, which tend to hold the flights in proper position at right angles to the frame when -lifting coal along the trough 52. The two parts of the conveyer-frame are connected by transverse bars 50, as shown in Figs. 1, 2, 12, and 1G, these bars extending outward and serving to support the trough 52 and plate l. The conveyer-franie is preferably composed of angleiron beams disposed parallel to each other on opposite sides of the carriage-posts and suitably bolted together.

A brace-bar 200 may be used for holding or assisting to hold the front end of the conveyer-frame in position to take up the coal, beingprovided with a pointed end 201, adapted to engage the walls or top of the .mineroom, and preferably with a ball 202 at its lower end adapted to engage socket 203, fixed on the front side of the extension of This brace-bar is preferably extensible, so that it may be elongated to hold or push said extension toward the pile of coal to be taken up by the endless conveyer. For this purpose it may be composed'of a tube 204;, a screw-threaded rod 205,'adapted to slide in said tube,'and a screw-threaded sleeve 206, engaging said screw-rod at the ower end of said tube and provided with a hand-wheel 207 for effecting the adjustment of the' screw rod relatively to the tube for elongating or shortening the brace-bar.

The loading -car is preferably a tractioncar, containingiu itself means for causing it to travel on the mine track. Means are shown for this purpose in Fig. 1, in which the same motor for operating the loadingy mechanism may be used for moving the car. In this case the driving-shaft of the compressedair motor 120 is provided with a pulley 210 (indicated in dottedliues in said figura) and one of the axles of the car isprovided with a pulley 211, also indicated in dotted lines, and a belt 212 connects said pulleys. This belt serves to transmit motion from the motor to the car-axle when the loading mechanism is out of operation or in normal inactive position. When the carriage is shifted on the car or the conveyer-frame is adjusted on the carriage out ot' said position to carry on the loading operation, the belt 212 maybe slipped off its pulley.

The compressed-air motor 120 may besupplied by may be connected with stationary air-cona liexible supply-pipe 230, which duits with which the mine is supplied in the usual manner. The traction-car may be provided with a winding-drum 231, adapted to wind. This drum is shown in Fig. 1 as fixed to a shaft mounted on the conveyerframe. A pulley'232 (shown iu dotted lines in said figure) is mounted on the shaftwof said drum, and a belt 233 connects itwith a pulley 234L on the driving-shaft of the motor, as indicated in dotted lines in said figure, whereby the drum .may be rotated by the motor for winding and nuwinding the pipe.

In the use of this machine for loading coal in a mine the loading-car is run into the mine'room, where the coal has been shot down, and the conveyer-frame thereof adj usted so that the depressed extension 60 will rest on the bottom or oor. The mine-car is placed adjacent to the loading-car under the rear extension of the conveyer, asindicated in Fig. 1. The conveyer is then started by steam, air, or other motive power employed, and the liights thereof move in a horizontal or approximately horizontal or non-verticalA plane around thefrontturn of 'said conveyor and, acting as a form Yof gathering device, scrape the coal from the mine-bottom onto the inclined trough 52, push it up said trough, and

-deliver it over the rear extension thereof into themnecar. The operator imparts a lateral movement to the carriageBO as required and causes the extension 60 to sweep around the floor toward the receding pile of coal. The operator also operates the separating mechanism to push the mine-car backward as desired to distribute the load. The brace-rod 200 serves to hold the depressed extension in contact with the pile of coal andmay be used as an auxiliary to the travel of the carriage to thrust said extension against the coal to be taken up. The mine-car is filled in very quick time by the stream of coal continuously delivered' by the conveyer, and when filled it is hauled away and replaced by an empty car.
